Computer furniture (Part 2)
Secondly, the computer furniture should be established so that it was comfortable and safe to work there. For this purpose it is necessary to choose correctly height of a table-top. The best variant here would be to adjust it within the limits of 680-800 mm. If you don????????t have such opportunity, we recommend you to choose tables in height of 725 mm (under the American standards - 740 mm). Adjust height of a chair so that the legs were placed under a table with comfort and did not become numb (free space for legs should be not less than 60 cm in height, 50 cm in width and 65 cm in depth). Put the monitor on distance of 60-70 cm from eyes. Position of the screen is considered correct if it stands vertically or is rejected from a vertical back on a corner 5-7 degrees. The level of eyes should be on the center of the screen or at the height equal of 2/3 distances from the bottom border up to the center.
For accomplishing these requirements, some manufacturers of computer tables equip them with their special monitor and shelves-supports adjustable on height. Such shelf is especially necessary if you deal with the monitor of the small size (15 inches diagonal). The keyboard should be placed far away from the edge of a table-top so that brushes of hands did not hang in air as it can lead to a chronic stretching of brushes. Well and at last, take care of that nothing could distract your attention. It is not necessary to place the bright or bright subjects near to a table, which may create patches of light on the screen of the monitor.
